Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: Net: Bridge – Reject descending VLAN tunnel ranges A pair of descending VLAN and tunnel IDs can pass the tunnel range span check. The VLAN subtraction produces a negative integer, which is converted to an unsigned value when...

CVE-2026-90243

A flaw was found in the Linux kernel's IOMMU/VT-d subsystem. During the tear-down of copied context entries, the kernel zeroes out parts of an entry before clearing its "Present" bit and invalidating related caches. This timing issue allows hardware to fetch a partially cleared entry that is stil...

CVE-2026-90114

This Linux kernel vulnerability affects the net: bridge subsystem. A pair of descending VLAN and tunnel IDs can pass the tunnel range span check because the VLAN subtraction produces a negative signed int, which is implicitly converted to unsigned when compared against the u32 tunnel ID delta. Wh...
